System requirements

SIMetrix and SIMetrix/SIMPLIS runs on Microsoft® Windows® platforms.

Virtual Machines and Emulators

Important: we only offer full support when running SIMetrix on supported operating systems running directly on physical hardware. This excludes
running SIMetrix in virtual machines or under emulation on non-supported operating systems. This doesn't mean you can't run SIMetrix on such systems
or that we won't support such systems at all. It does mean that we will only be able to help with problems that can be reproduced on a supported OS.

In particular, we can not help with problems with dongles if SIMetrix is running in a virtual machine or under emulation.

Operating System – 64 bit Versions

The following operating systems are fully supported for SIMetrix and SIMetrix/SIMPLIS 64-bit versions:

Multicore support

Some processors increase the apparent number of CPUs by using a technology called "Hyperthreading". SIMetrix and SIMetrix/SIMPLIS do not directly use hyperthreaded (also known as "logical") CPUs.

The greatest benefit from multiple cores is achieved when running Monte Carlo analyses and other multiple analysis modes. This applies to both SIMetrix and SIMPLIS simulators. For this
application, typical performance benefit of about 75% of the core count can be achieved. So for 4 cores a Monte Carlo run may execute about 3 times faster.
The SIMetrix simulator can also exploit multiple cores to gain a speedup for single runs, but the performance benefit achieved is much more modest and typically there is little benefit
in having more than about 4 cores.

System requirements for older versions

Older versions of SIMetrix will run on the operating systems supported at the time of their release. In general we have found that all 32-bit
Windows® versions of SIMetrix back to version 1.0 will usually run on any 32-bit Windows® operating system, but often need special install procedures. However, we have not tested every version of SIMetrix
with every version of Windows® and can make no guarantees or offer any support for non-supported operating systems.

There can be problems with older versions running on 64-bit systems. In particular versions 5.3 or earlier using portable licenses (i.e. with a USB security key) will not
work with any 64-bit system.
